Apple Thunderbolt Cables are connection accessories from Apple for devices that support Thunderbolt 1 or 2.


The cables are available in 0.5 and 2.0m lengths and support two independent channels of Thunderbolt data transfers at up to 10Gb/s each. Devices that support Thunderbolt 2 can bond the two channels to support data transfers at up to 20Gb/s.

The Apple Thunderbolt Cable can be used to connect high-bandwidth Thunderbolt peripherals or for fast networking between Thunderbolt-equiped computers. It can also enable target disk mode on Macs for fast data access or system migration.


Usage of the cables with Thunderbolt 3 or 4 devices require a Thunderbolt 3 to Thunderbolt 2 Adapter. Though Thunderbolt 3 cables are interchangeable with USB-C, Thunderbolt 1 and 2 cables cannot carry USB signals.

Thunderbolt ports are also backwards compatible with Mini DisplayPort peripherals.[1] However, the Thunderbolt 3 to Thunderbolt 2 Adapter does not support Mini DisplayPort signals.[2]
